1. The objective of this project is to develop a wideband ground plane for a long slot aperture to support greater than 20:1 operation (.2 to 2GHz) while maintaining a low effective dielectric index for ease of feeding. Our approach is to introduce a reflective surface composed of a high impedance surface (non-conductive ferrite) in the outer region tapering to an electrically conductive surface at the center of the slot. The ferrite material in the outer region aims to emulate the free-space antenna gain at low frequencies whereas the conductive center region serves to increase gain at the higher frequencies. |
